Weapon sight

A weapon sight having a peep sight mounted to a flexible, curved transverse cross-section bar movable across a curved surface interior to a housing. The flexible bar, which is preset and locked at a fixed range, is stored horizontally below the cover of the housing and assumes a vertical position with the peep sight at the fixed range when the cover is opened. A protuberance from the other end of the bar produces an audible and tactile indication of fixed variations in range. The range adjustment knob drives the bar with a single pin.
